摘要
在稠油热采地震监测中,储层特性的变化主要是通过弹性波参数的变化才最终表现为地层速度和实际地震响应的变化.因此,在一定条件下,弹性波参数应当是储层特定变化最直接和灵敏的标志.本文详细叙述了弹性波阻抗反演的方法,并将其应用于稠油热采地震资料的反演和解释中,结果表明弹性波阻抗反演用于稠油热采地震监测是切实可行的.
The variation of reservoir characteristics mainly show the changes of reservoir velocity and actual seismic response caused by the change of elastic parameters In the process of seismic monitoring of the heavy-oil thermal recovery. For this reason, elastic parameters should be the most direct and sensitive indication for the variation of reservoir characteristics under certain condition. In the paper, the method of elastic impendence inversion is introduced in detail and used in the inversion and explanation of seismic monitoring data. Results show it is feasible for elastic impendence inversion to be used in seismic monitoring of the heavy-oil thermal recovery.
